Interpolation of 2D non-uniform data


#1

Hi all,

I have 3 arrays:, X, Y and Velocity, which contain velocity measurements at non-uniform (x,y) locations.

I would like to create a 2D figure of interpolated velocities values.

I know there is the https://github.com/tlycken/Interpolations.jl package, however, since I am new to Julia I am having trouble in understanding how can it solve my problem.

If anyone can send along some resources for my specific problem, or perhaps explain how the above package ca be used, it would be greatly appreciated.

thank you

Have you seen https://github.com/kbarbary/Dierckx.jl: “Fit and evaluate 2-d splines at unstructured points.”

I created this NoteBook illustrating how to interpolate with GMT. Others will follow showing figures prepared with GMT.
